Then you must check the current resource allocations for the
computer and your expansion unit, and select the
available resource values by
using the ThinkPad Features program.
This appendix, listing the default and optional hardware settings, describes how to avoid system resource conflicts. It also describes how to do a network remote program load and how to start the computer from an ATA PC Card.
When a new option such as a PC Card is installed, the computer might not operate correctly because of conflicting settings for IRQ (interrupt) levels, I/O addresses, DMA channels, and memory addresses.
To avoid these resource conflicts,
you must know the hardware
requirements, such as IRQ level and I/O addresses,
for each option and program as shown in their
manuals.
ThinkPad Features program:
reference #15.
Then you must check the current resource allocations for the
computer and your expansion unit, and select the
available resource values by
using the ThinkPad Features program.
When you want to install a new Ethernet PC Card in the computer, you need to assign an IRQ for the PC Card. An Ethernet PC Card generally requires IRQ5 as a default interrupt level; however, IRQ5 has already been occupied by the audio device in the computer. You need to change the IRQ for the audio device when you use the Ethernet PC Card as follows:
reference #123.
You can see from the list of default settings on reference #123 which system resources are already used by the devices in the computer.
To do a network remote program load (RPL):
The following are the resources for a token-ring PC Card and an Ethernet PC Card:
IRQ5 is the default setting used by the Sound Blaster emulation. To do an Ethernet PC Card RPL, change the IRQ for the Sound Blaster emulation, or disable it with the ThinkPad Features program or the SB PS2 command.
A window appears at the bottom of the screen for you to select the RPL speed.
To start the computer from an ATA PC Card:
The following are the resources for an ATA PC Card:
The PC Card (PCMCIA icon) should not be set to follow the computer hard disk drive (HDD icon) in the list. If the HDD icon is already in the drive-startup sequence, click on the Reset icon; then set the sequence so that the PC Card icon is before the HDD icon.
The following table summarizes the available
system resources for the computer and
expansion units.
Values in
parentheses are alternative values that are selectable in
the ThinkPad Features program
or application programs.
The default values are highlighted.
